Abstract: In one example a method of fracture reduction includes imaging, intraoperatively, a fractured bone of a patient to obtain a first representation of the fractured bone in a computing system. The fractured bone defines at least a first bone fragment, and a second bone fragment that is separated from the first bone fragment by a fracture. The method includes imaging, intraoperatively, a contralateral bone of the patient to obtain a second representation of the contralateral bone in the computing system. The method includes generating, intraoperatively in the computing system, a mirrored representation of the first representation or the second representation. The first representation is compared to a representation of a desired orientation of the fractured bone, where the representation of the desired orientation is the mirrored representation of the second representation.

Abstract: Disclosed is a joining element (10), especially a suture material for surgical use. The joining element (10) is composed of a first material (12) that is essentially rigid during impingement by a relatively short-lasting tensile load on opposite sides as well as a second material (11) which is connected to the first material. The second material is substantially rigid during impingement by said tensile load on opposite sides while contracting slowly during a second period of time that is longer than the first period of time.

Abstract: An implant for insertion into a disc space between vertebrae, wherein the implant includes a spacer portion, a plate portion coupled to the spacer portion, two bone fixation elements for engaging the vertebrae and a retention mechanism for preventing the bone fixation elements from postoperatively backing-out of the plate portion. The retention mechanism may be in the form of a spring biased snapper element that is biased into communication with the bone fixation elements so that once the bone fixation element advances past the snapper element, the snapper element is biased back to its initial position in which the snapper element interfaces with the bone fixation elements. Alternatively, the retention mechanism may be in the form of a propeller rotatable between a first position in which the bone fixation elements are insertable to a second position where the bone fixation elements are prevented from backing-out.

Abstract: The present invention is directed an anchor assembly for use in spinal fixation to interconnect a longitudinal spinal rod with a patient's vertebra. The anchor assembly preferably includes a bone anchor, a body with a rod-receiving channel, an insert member (preferably a bushing), and a locking cap with a saddle. The anchor assembly preferably enables in-situ assembly where the bone anchor may be secured to the patient's vertebra prior to being received within the body of the bone anchor assembly. Accordingly, the anchor assembly enables a surgeon to implant the bone anchor without the body to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the body may be snapped onto the bone anchor and a spinal rod may be inserted into the rod-receiving channel.

Abstract: Various systems and methods of delivering an implant to a target location of a body vessel are disclosed. A detachment system can include a tubular body including a lumen extending therethrough and a distal tube on a distal end of the tubular body. A loop wire can be affixed at a first end to the tubular body and can include a loop opening positioned approximate a distal end of the distal tube. A pull wire can extend through the lumen. A hook wire can extend radially through a sidewall of the distal tube and into the lumen. The hook wire can be positioned around a pull wire portion and tensioned such that the pull wire portion abuts the distal tube and provides frictional resistance between the pull wire portion and the sidewall of the distal tube. The frictional resistance can be effective to inhibit premature detachment of the implant.

Abstract: A motor-driven orthopedic impacting tool is provided for orthopedic impacting in the hips, knees, shoulders and the like. The tool is capable of holding a broach, chisel, or other end effector, which when gently tapped in a cavity with controlled percussive impacts, can expand the size or volume of an opening of the cavity or facilitate removal of the broach, implant, or other surgical implement from the opening. A stored-energy drive mechanism stores potential energy and then releases it to launch a launched mass or striker to communicate a striking force to an adapter in either a forward or reverse direction. The tool may further include a combination anvil and adapter and an energy adjustment mechanism to adjust the striking force the launched mass delivers to the adapter in accordance with a patient profile.

The patient-specific-bone-graft cage can construct an essential portion (including complex thin anatomical structures) of or substantially the entirety of the mid-face region (e.g., to fill a void in a damaged orbital region), which enables an improved structure reproduction and simplification for the surgeon. For example, the patient-specific-bone-graft cage may be formed based on the contour of the periphery defining the void in the damaged region, and require less modification by a surgeon compared to graft cages formed only by mirroring techniques or normalized models.
